COMP Cams Valve Locks Eb 5/16in 7DegMost people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock.

I have a couple of kayaks made of various resin types, and all were showing severe signs of oxidation on their paint jobs. The newest is probably 20 years old, so you can imagine the oxidation. All I can say is, I was greatly surprised and pleased with the result. Other than the scratches, the oxidation was almost entirely removed! I'm a true believer in this stuff!
